How can the developer securely provide temporary access to the objects that are stored in the S3 bucket?
Set object retention on the files. Use the AWS software development kit (SDK) to restore the object before subsequent requests. Provide the bucket’s S3 URL.
Use the AWS software development kit (SDK) to generate a presigned URL. Provide the presigned URL.
Set a bucket policy that restricts access after a period of time. Provide the bucket’s S3 URL.
Configure static web hosting on the S3 bucket. Provide the bucket’s web URL.
Explanations:
Object retention is used for preventing object deletion or modification, not for temporary access. The AWS SDK can restore the object, but this does not securely provide temporary access.
A presigned URL allows temporary access to an object in S3 without exposing the object publicly. The URL can have an expiration time, ensuring limited access to the object.
A bucket policy can control access, but it cannot be dynamically used to generate temporary access with an expiration time for a specific request. A presigned URL is the correct method for temporary access.
Static web hosting is used to serve content publicly from an S3 bucket and does not offer secure, temporary access control. It exposes the object without a defined expiration time.
I rank that the answer is:
Use the AWS software development kit (SDK) to generate a presigned URL. Provide the presigned URL.
